Applications of carbon nanotubes-based electrochemical biosensors

Abstract

Electrochemical biosensors are newly developed devices and used for various purposes, which is applied in plenty of fields, including medicine, agriculture, food production, and other fields that require the detection of certain particles. Carbon nanotubes (CNTs) are useful nanomaterials in many fields and can be further divided into single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs). These CNTs with special structure and property make many things possible, such as for development of a diverse of different sensitive electrochemical biosensors. This research aims at investigating the applications of carbon nanotube-based electrochemical biosensors in various fields. In the introduction, some basic information about electrochemical biosensors is outlined. The composition and classification of electrochemical biosensors are provided in detail, and the advantages of using carbon nanotubes in electrochemical biosensors are explained specifically. This research concludes with the working principle of electrochemical biosensors and principles of enzyme immobilization. Applications of carbon nanotubes-based electrochemical biosensors are introduced, where specific reaction equations and more detailed applications are also mentioned in this section. The current limitations of electrochemical biosensors are provided at the end of this research.
